Terms of Use
Effective 24 September 2026.
XLSX Editor is licensed to you through the Microsoft Store under the Microsoft Standard Application License Terms. HAYAH is the licensor. These terms add the following.
Price
This version is free, with every feature available and no in-app purchases. If a future version adds paid options, they will be described on this page and in the Store listing before you buy.
Your files
You are responsible for having the right to open and edit the files you use with the app. Keep backups of important files. Some formats cannot hold everything a workbook contains (for example, CSV keeps only the values of one sheet, and .xls is limited to 65,536 rows); the app tells you before it saves in such a format.
Not Microsoft Excel
XLSX Editor is an independent app by HAYAH. It is not Microsoft Excel and is not affiliated with or endorsed by Microsoft. Microsoft and Excel are trademarks of the Microsoft group of companies.
Third-party components
The app uses third-party components, including Syncfusion Essential Studio, under their own licenses. Their notices are listed in the app under About.
No warranty
The app is provided as is, to the extent permitted by law. HAYAH is not liable for indirect or consequential losses arising from its use.
